Albemarle's $1 billion Kemerton plant, page-10

I love Maths, and not good in drawing (will make an architect is a bit upset). But I believe that numbers and figures give a correct picture of everything and make a beautiful truth and sustainable development of everything.
Basic Maths on WSI, the current book at 33 mil is tempting, BUT what is the margin % ?
Let's saying 20%, we will have around 6.6 mil positively coming into the book in the next 4D.
Take 6.6 / total share of 420 mil = 1.5 cents EPS. Apply PE = 10 then we have 15c SP. OMG, I should put my house to this one.
BUT, hang on a second, is it true ?
10% margin to be safer, we still get 7.5c for SP.
Wait a minute, is it true .... ???
I will remain overly cautious about this stock until I see the real figure in upcoming 4C or later in 4D.

P/S: Never put your house at any risk whatsoever in life, because you will need a place to crash upon falling.
My wife have 75% ownership of the house anyway.
